Question

pls solve this ..i will mark as brainliest... quick plz​

Answer 1

Answer:

a) 4S, n=4 l=0》n+l=4. and for 3P n=3 l=1》n+l=4.

But 4S has more energy than 3P.

because, according to (n+l) rule.If the value (n+l) is same for both then the sub shell which has larger 'n' value will have more energy.

b) 3P,(n+l)=3+1=4.

3d,(n+l)=3+2=5.

Therefore, 3d has more energy.

c)2s,(n+l)=2+0=2.

3d,(n+l)=3+2=5.

Therefore,3d has more energy.

d)3d,(n+l)=3+2=5.

4p,(n+l)=4+1=5.

4p has more energy than 3d as per the reason told in the 1st option.
